ESD7002WTT1G

onsemi · TVS · SC-70-3

ESD7002WTT1G from onsemi, in a SC-70-3. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 I/O1 passive Cathode (Style 4) flow-through I/O line 1 protected against ESD up to ±8 kV contact / ±15 kV air (IEC 61000-4-2), 0.3 pF typical to GND, VRWM 16 V.
2 I/O2 passive Cathode (Style 4) flow-through I/O line 2 protected against ESD up to ±8 kV contact / ±15 kV air (IEC 61000-4-2), 0.3 pF typical to GND, VRWM 16 V.
3 GND power_in Anode (Style 4) common ground reference for the ESD protection diodes on I/O1 and I/O2.
